Total load on distribution board

[SPARTYKUS]

I could see some bl**dy big main switches around.....not to mention tails...be getting up to 220 amps with a CU in an average semi.

Whats wrong with that?

for a few seconds.

If you're asking a question like this, then the HNC you say you have, isn't in electrical Engineering!!
So you're either an apprentice or another wannabe Electrical Trainee electrician!!

Hi farraday. Welcome to the forum
First of all I'm presuming you mean a 250A isolator and not a 250A breaker.
Your question was answered in post 2 by Marvo. Read post 2 again.
Also depends on when the 3 phase board is feeding and if you can apply diversity.
Not wanting to sound negative (but always end up doing so) but why do you need to know and I'm kind of going along with Eng54 first sentence in post 17.

Thanks for the sensible reply mate, very much appreciated.

Regarding my HND, I did not say it was electrical so there's no need to question my qualifications. It's in refrigeration design.

I understand that forums are close knot communities as I use several others. Some of the responses in here to a new member and someone wanting to learn are pretty shocking g and certainly doesn't paint the board in a good light. We you not all just starting out and trying to learn at some point?

I may have come across a bit harsh. soz for that....
If you are not an electrical and are just curious then you should say so in your post. Its good that we all question and earn things.
Did you find out your answer?
